Liquid Helium Transfer Line.How do you transfer a liquid
that is at minus 450 F (or -270 C) ? Remember that the air around us
becomes a liquid at about -150 F. Helium gas becomes a liquid at -450 F
!! Well, you use a Liquid He Transfer Line. 6 feet evacuated flexible
section with Bellows valve for pumping the air from around it,
standard 28 inch long
dewar legs on both ends
Go on Google and search for Liquid He Transfer Line. This item is
advertised for $2,500 ! We are done with
our experiments and a lucky person can have this Liquid He Transfer Line
for $500.

Now the question is how on earth do we ship something shaped
like this ?! Photo
